AS POPE FRANCIS prepares to release his encyclical on climate change, it’s worth remembering exactly how far the conversation on religion and the environment has come in the past quarter-century.
When I wrote The End of Nature back in the late 1980s, there was very little religious environmentalism. Liberal churches believed that ecology was a subject to be addressed once you’d finished with war and poverty; conservative churches viewed it as a way station on the road to paganism. And Christians in general still reeled under the idea, propounded by Lynn White in an influential essay in Science magazine, that the Genesis call for dominion had led directly to the destruction we saw around us.
In those early days, there were a few wayfarers on this path. Thomas Berry, for instance, and even more important a pair of academics—Mary Evelyn Tucker and John Grim—who picked up his clues and sweated blood to assemble theologians from around the world and search every tradition for the roots of ecological thinking. Episcopal Power and Light—now Interfaith Power and Light—was an early and successful effort at congregational action; Shomrei Adamah (Guardians of the Earth) was an early effort in the Jewish community that has blossomed into many flowers.
More senior figures began to join. Patriarch Bartholomew, leader of 400 million Eastern Christians, became known as the “green patriarch” for his straightforward reckoning that environmental desecration was just that, a sin. Desmond Tutu has called climate change the “human rights challenge of our time.” Now the pope. “It is [humanity] who has slapped nature in the face,” Francis said. “We have in a sense taken over nature.”
There’s pushback still, of course. When the pope made his remarks, a blogger at the conservative journal First Things announced, “Francis serves an environmentalist mindset that, unlike the traditional ethos of conservation, views [humanity] as a parasite.” Oof; them’s fighting words. And from the corporatist, compromised center, there’s the usual dismay at having to take sides. The Interfaith Center on Corporate Responsibility, for instance, has done its best to blunt the growing movement for fossil-fuel divestment, arguing that “companies aren’t the enemy.”
Happily, though, the momentum is clear. Denominations such as the United Church of Christ and the Unitarians have called for divestment; Methodist colleges and Catholic research universities are joining in. Religious people do understand that there are enemies in this fight—that the companies who melted the Arctic and then moved to drill for yet more oil in its open waters meet any theological test you could devise for radical irresponsibility.
This movement unites young—who will have to live for decades with a changed planet—and old, who will have to go to their graves knowing that we’ve left a damaged planet behind. It reaches across ideology—the question of how and whether we evolved is less pressing than the fact that we’re now running Genesis in reverse.
There’s a streak of sadness that runs through this movement: Clearly we’ve failed to responsibly exercise dominion (we’re the bad babysitter, who takes the 2-year-old out for a tattoo and some piercings). But there’s also a streak of joy. Unlike secular environmentalists, we’re entitled—if we work as hard as we know how to work—to imagine that some force will meet us halfway. Despair is optional, thank heaven.
